Pronunciation: 
Brit. //
U.S. /i/
Etymology: the fifth letter of the Roman alphabet, represents historically the Semitic ?, which originally expressed a sound resembling that of h, but was adopted by the Greeks (and from them by the Romans) as a vowel, the pronunciation of which probably varied from the ‘mid-front’ /e/ to the ‘low front’ /ɛ/ vowels of Bell's system. In the Roman, as in the earliest Greek alphabet, the letter represented the long as well as the short quantity of the vowel. There are reasons for believing that in Old English the short e had two sounds, possibly /e/ and /ɛ/; the Old English long é seems to have been sounded approximately as //.
 
The sounds now expressed by E in standard English are the following:1. /iː/in be/biː/2. /ɪə/in here/hɪə(r)/3. /ɛə/in there/ðɛə(r)/4. /iː/, /ɪ/in acme/ˈækmiː/, /ˈækmɪ/5. /ɛ/in bed/bɛd/6. /ɜː/in alert/əˈlɜːt/
Exceptional sounds are (7) // in eh!, (8) /ɪ/ in England, English, and (9) /ɑː/ occurring before r in clerk, sergeant, and in various proper names, as Berkeley, Hertford.
 
In unaccented syllables it has the obscure sounds:
 
10. /ɪ/in remain /rɪˈmein/, added /ˈædɪd/11. /ə/in moment /ˈməʊmənt/, father /ˈfɑːðə(r)/12. the mere voice-glide /ə/as in sadden /ˈsæd(ə)n/
 
In foreign words not fully naturalized certain other sounds occur: the French en occas. retains in English use its two sounds of /ɑ̃/ and /æ̃/, as in ennui /ɑ̃nyi/, bon-chretien /bɔ̃kretjæ̃/; the French unaccented e preserves the sound of /ə/ in words like eau-de-vie /o də vi/; and the French é that of /e/ in a few words, as café /kafe/.
 
E is also the first element in many vowel-digraphs, most of which have more than one pronunciation.
(1) Ea   is usually sounded //, as in bead   /biːd/; exceptionally as // in break  , great  , steak  . It frequently represents /ɛ/ in cases where that sound descends from a long vowel or diphthong, either original, as in thread   /θrɛd/, dead   /dɛd/, or acquired in Middle English through position, as in stead   /stɛd/. When followed by r   it has the sounds of /ɪə/ as in ear   /ɪə(r)/, of /ɛə/ as in pear   /pɛə(r)/, and of /ɜː/ as in earth   /ɜːθ/, /ɑː/ as in heart   /hɑːt/. In final unaccented syllables it sometimes becomes /ɪ/ as in guinea   /ˈɡɪnɪ/.
 
(2) Eau  , found only in words of French origin, is sounded /juː/ in beauty   and its derivatives, and // in a few proper names, as Beauchamp   /ˈbiːtʃəm/; in all other cases it is /əʊ/ or /o/, as in bureau   /ˈbjuːrəʊ/, rouleau   /rulo/.
 
(3) Ee   has the sound of // as in feel   /fiːl/, and before r   that of /ɪə/, as in peer   /pɪə(r)/. In been   many persons sound it as /ɪ/; it has also this sound in breeches   /ˈbrɪtʃɪz/, coffee   /ˈkɒfɪ/.
 
(4) Ei   has the sound of // chiefly in the combination cei  , as in receive  ; also in teil  , and in Scots words, as teind  . In other cases its usual sound is //, as in vein  . In either  , neither  , it is variously sounded // and //. In a few words, on account of German or Greek etymology, it is pronounced //, as in eider-down  , ophicleide  . In unaccented final syllables it becomes /ɪ/, as in foreign   /ˈfɒrɪn/, sovereign  .
 
(5) Eo   (as a digraph) is sounded // in people  , /ɛ/ in leopard  , and /əʊ/ in yeoman  .
 
(6) Eu   has the sound of /juː/, and when followed by r   that of /jʊə/, as in euphony  , Europe  . (After l   or r   the first element in these diphthongs is wholly or partially obscured: see L n., R n.) In a few French words not fully naturalized eu retains its original sounds /œ/ and /ø/.
 
(7) Ew has the sound of /juː/, as in new /njuː/, Matthew.
 
(8) Ey is sounded // in key, and // in obey, they, prey; it occurs most frequently in unaccented final syllables, with the sound /ɪ/, as in donkey /ˈdɒŋkɪ/, money. In eye and its derivatives and compounds it is pronounced //.
 
The cases in which E is silent are very numerous.
The rule may be laid down that (except in foreign words not fully naturalized as to form) a final e is never sounded when there is another vowel in the word. The silent e is due primarily to the Middle English obscure -e ( < Old English a, e, o, u, or < French e), which continued to be written long after it ceased to be sounded. In imitation of the cases in which the silent e had this historical justification, it was in 16th cent. very frequently added to almost all words ending phonetically with a cons.; when the preceding vowel was short and accented, the final cons. was doubled, as in bludde, bedde for blood, bed; a mute e after a single consonant implied that the preceding vowel was long. In present spelling the use of silent e has been greatly narrowed, but it is retained in the following cases: (1) When it serves to indicate that the vowel in the syllable is long; e.g. in wine/waɪn/ compared with win /wɪn/, paste /peɪst/ compared with past /pɑːst//pæst/. When the quantity of the vowel is already shown by the use of a digraph, the e is no longer added, e.g. in soon, mean (in 16th cent. often soone, meane), unless the final cons. is s, z, or the voiced th /ð/, as in house, breeze, sheathe. (2) When a word ends phonetically with certain consonants which custom does not permit to be written in a final position, as v, and l, r after consonants. (3) Where the silent e affects the pronunciation of a preceding c or g. (4) After s or z preceded by a cons., as in purse, pulse, corpse, bronze, furze. (5) In words like infinite, rapine, etc., where the vowel of the final syllable has become short since the establishment of the existing rules of spelling; and in words adopted < French. (6) In some anomalous cases of diverse origin, as are, were, come, done, gone, some, one, none. The silent e is omitted before flexional suffixes beginning with a vowel, as in moving; before -able it has been usually retained, as in moveable, loveable, unmistakeable, though many writers now prefer to omit it, esp. when the verb is a polysyllable. Before suffixes beginning with a cons. the mute e is nearly always written; in abridgment, acknowledgment, fledgling, judgment, nursling, it is commonly omitted, but usage is divided except in the last instance; in this Dictionary the e is retained after dg, in accordance with general English analogies.
